Portion of display screen having graphical user interface with transitional icon



FIG. 1 is a front view of a portion of a display screen having a graphical user interface with a transitional icon, showing our new design and illustrating a first image thereof; and,

FIG. 2 is a front view of a second image thereof.

The appearance of the transitional icon in the graphical user interface sequentially transitions between the images shown in FIGS. 1 and 2. The process or period in which one image transitions to another image forms no part of the claimed design.

The outermost broken line rectangle showing exterior edges of the display screen, the second-outermost broken line rectangle showing interior edges of the display screen, and all broken line elements between the outermost and second-outermost broken line rectangles are included for the purpose of illustrating portions of the display screen to which the claimed design is applied. All broken lines within the second-outermost broken line rectangle show the remainder of the graphical user interface and are included for the purpose of illustrating environmental structure. All subject matter shown in broken lines forms no part of the claimed design. 

CLAIM The ornamental design for a portion of display screen having graphical user interface with transitional icon, as shown and described.
